To all whom t may concern: u

Be it known that I,FRANK R. CHILDREN,

a citizen of the `United States, residinginy Council Bluffs, in the county of Fottawattamie and State of Iowa, have invented a new and useful Improvement in Hog-Oilersnbf which the following is a specification.

My invention relates in general' to hog oilers and has more particular reference to devices vof this character arranged to cause an automaticapplication of oil or other medicament whenever a hog rubs there-` against.`

Thepurpose of'a device of this character is, generally speaking, the `application of oil or the like to a hog for the killing of lice and other' vermin. The intention is that a hog shall rub against a member provided for the purpose withythe'result that oil will be delivered vupon him, this oil `being delivered in sufficient quantity to cover an appreciable portion of the skin surface.

A principal object of the inventionis the provision of such a device which will permit the hog to rubhis back as well as his sides thereagainst, so that the oil may run down over his flanks and on to his legs and under his belly.

A further object of the invention is thev provision of such a device which will insure a maximum effect through the utilization of a minimum amount of verminv exterminating material. v

A further object of the invention is'the provision of means for varying the amount of oil delivered tosuit changes of-fiuidity resulting from seasonal differences in tem- A "urther object of the invention is the provision ofy such a device which will be of economical manufacture, the parts of which will not be readily damaged ordisarranged under the roughk usage ordinarily given such devices.

Other objects and advantages of the invention will be apparent asit is better understood from the following description when considered in connection with the accompanying drawing illustrating a preferred embodiment thereof.

On the drawing,

Figure 1 is a side elevation of a hog oiler embodying my invention;

i" ing. a is a ImagnaanniV partiti 'Sti-.Cuori throughv the same;

Fig.v 3 is a section taken substantially ony the line of Fig. 2;

' Fig. 4 is a similar view taken substantially on the line 4?/Lof Fig. 2;

Fig. 5 isy aside elevation of the mounting fortlie oiler; and i l i ,Figfr 6 is a lperspective view of the yvalve operating lever providedv in the presentinstance.

The'hog oiler shown on the drawing and embodying inyinvention comprises a supporting base 7 in which is secured a stationary-shaft S'carryingat its upper end, a reservoir 9 `foi'the containing of 'oil orother vermin eXterminating material. member 10 againstwhichtlie hog may rub `in the present instance embraces the 'shaft 8 and this member, f whenv the hog rubs thereagainst, operates a lever 11 controlling a de'-- livery7 valve 12. l

rThe support 7 is provided with a base plate 13 which `maybe secured to any suitable permanent support'll: bybolts 15 or the like. It provides an linclined socketpl in which is secured an end' 17 of the shaft 8, thus disposing the shaft 8 in vinclined position, The inclination, about forty-five de'- grees', given this shaft` is sufficient to bring itfwell over theback' of th e hog and the length A`of the shaft is sufficient to permit the hog to get well under vit when he rubs thereagainst. The upper end of the vshaft 'Slis threaded at19 and is engaged in an inclined Specification of Letters iatent. Patented 0015. 2, 1917. Application nien April 19, isis; ;sria1i\io.'22,289.\ i V` socket 21 formed iny the base of thereser- I voir 9, the inclination of this .socket being such that the reservoir 9 maintains the upright vertical position shown.

The rubbing member '10 inthe present iny stance consists of a sleeve having an inter-' nal; diameter much greaterthan the external diameter of the shaft 8. This sleeveloosely embracestlie shaft'and is movable inv several directions when a hog rubs thereagainst, being held by gravity in the position shown inFig. 1 and being capable of being moved sirable as it removes considerable dirt andv exposes the verminto the oil which is applied, as will `be later described. Italso provides a pleasing sensation to the hog and encourages vlllIl- DO make usel ofltheioilen AnyV movement of 4 the sleeve 10 .causes an t.

operation of the lever 11 which in turn operates. the valve 12. This lever consists` of a bifurcated end forming arms 22 adapted lto be'fdisposed jupon opposite sidesI Vof the v lug 23. The arms 22 areperforated and are 'pivotally secured to the'lugv 23 by a pivot pin 2.4;, The ,forward end of the lever is flat and v curved downwardly at 25 ltorestupon the in engagement With the sleeve. manifest that any lateralmovement of thev sleeve will ,operate the lever by pressing sleeve 10, thelower extremity of the lever being c'ut away arcuately at 26 to maintain it It will be against' it and upward or longitudinal move'-` ment will producelike results through engagement of `the lever .with lthe end of thesleeve or` by the engagement with the roughened ,surface of the sleeve.

1 Iny 'order that av predetermined' quantity only oioil may be delivered to the hog,the

valve A12 is given the peculiar construction to be -now described. A valve casing 27 is screwed into the bottom of the reservoir 9, vthis casing having at its top avalve seat 28 beneath` which a port 29 is provided. This port `communicates with an enlarged chamber Oimmediately therebeneath, the chamber 30 extending to and through the lower end of the'casing. A valve member is positionedin this casing and this valve member valve head Slis provided with a flutedfstem portion 32 which permits passage of 'the liquid'through the port 29 and yalso with a threaded portion Bton which is engaged the valvehead 35, also having a uted stem 36 movable in the chamber 30, thisv stem` providing. passageways 38.: The head 35 is i adapted'to seat against the lower end of the valvecasing tojclose the reservoir when the f. valve 1s raised to its upper limit. A spring 39, is, po's'itionedA betweenthe. upper end of the chamber 30` and the vupper end of the valve stem 36, normally holding the valve lin lower position. The lower end of the portion totthevalve stemis lengageable theheadofabolt 4l adjustably secured man apertures@ in .the'lever `11, vupward movement of thelever bringing the head of, .thefbolt 4l, into-'engagement with the lower end "of the threaded portion' 34 of the .valve stem, 4thereby lifting the lower valve head l 35 r.and :the upper valvezliand permitting adisch-arge oit oily which ...Hows `downwardly through the passages 33, through the' chamfber 30, through the passages 38 and onto the wide end. 25 of the lever, oli' which it f iiows either on to the hog or on to the sleeve 10. and ,thenceon .to the hog. `This causes a limited and predetermined amount of oil to be delivered Aand thereby prevents an ov-erdischarge ci oily should the'hog occupy Aa lengthened period .in rubbing against the member Yor sileevelO. ,'lhe bolt l1 may be turned vto producea proper delivery in both coldand `hot weather and in accordance with the lrelat iv, e fluidity at these times.

KVM,I t willbe rmanifest thatthe device consistsof few .an d simple parts which may be Icheaply provided land which,` when properly assembled, prrwide,` llittle opportunity forthe need .of repair.

It is thought that the. invention andmany ci.` itsattendan-t advantages will be understoodfromr the foregoing description, and

it 'willbeapparent thatvarious rchanges may be madein .the-orm, :onstruction and arrangement :of the parts f without departing from; the spirit and scope yof the invention orsacricing any of: its material advantages, v the form hereinbetore describedbeing merely a preferred embodiment thereof.
